How to replace last comma in string with and using php?

To replace only the last occurrence, I think the better way is:

$likes = 'Apple, Samsung, Microsoft';
$likes = substr_replace($likes, ' and', strrpos($likes, ','), 1);

strrpos finds the position of last comma, and substr_replace puts the desired string in that place replacing '1' characters in this case.

How remove the last comma in my string?

I am guessing that you are trying to take an array of strings of space separated ids and flatten it into a comma separated list of the ids.

If that is correct you can do it as:

$arr = [
    'abc def ghi',
    'jklm nopq rstu',
    'vwxy',
];
$list = implode(', ', explode(' ', implode(' ', $arr)));
echo $list;

output:

abc, def, ghi, jklm, nopq, rstu, vwxy

Removing last comma from a foreach loop

Put your values in an array and then implode that array with a comma (+ a space to be cleaner):

$myArray = array();
foreach ($this->sinonimo as $s){ 
    $myArray[] = '<span>'.ucfirst($s->sinonimo).'</span>';
}

echo implode( ', ', $myArray );

This will put commas inbetween each value, but not at the end. Also in this case the comma will be outside the span, like:

<span>Text1<span>, <span>Text2<span>, <span>Text3<span>

                                                        'terms' => $catVal->term_id
